U Ni-l T -EtD STATES} attests v Application filed March 24, 1925. Serial No. 17,964.

The present'invention relates to a flue stop, and aims to provide a novel and improved device of this character, having a plate arranged in the openingleading to the interior of a chimney for preventing the intense heat in the chimney from contacting with a cover plate arranged where the opening communicates with a room, said plate arranged in said opening lessening the danger of fire and preserving the outer side or finish of said cover plate. I 7

Another object of the invention is the provision of a heat receiving plate attached to a cover plate so that said plates may be folded in a compact form when not inuse, said heat receiving plate having means thereon for.

holding same together with the cover plate in a position while closing a chimney flue.

It is also an object of the invention to provide a flue stop of the kind indicated, which is simple and substantial in construe tion, which can be manufactured GCQIIOIIli- (:ally, and which will be thoroughly eflicient and practical in use.

ith the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of What is claimed, without departing from the spirit of the invention.

The invention is illustratedin the accompanying drawings, wherein:

Figure 1 is a side elevation of my improved device showing the same applied in a flue opening, I

Figure 2 is a section taken on line 2-2 of I Figure 1, and v j Figure 3 is'a section taken on line 33 of Figure 2. a I

In carrying'out the invention, the numeral 5 designates the cover plate, which is slightly dish shaped and is provided with an outwardly extending flange 6 for engaging the wall of'a room adjacent the point where the flue opening from the chimney communicates. Arranged upon the inner face of the cover plate 5 is secured a pair of angle members 7 each-having pivotally connected thereto one end of a pair of pivotallv connected links 8 and 9, the opposite ends of which are pivotally connectedto similar angle members 10 secured to the heat receiving plate 11. Each set of links 8 and 9 have their joining ends pivotally connected. as at 12. so as to permit the heat re'ceivingplate 11 to be i Iolded in a position adjacent the inner face or surface or the cover plate 5. j I

Attached to the center and arranged upon theinner side of the plate -11 is a strip of spring steel material 13 whichextends across the plate 11 and has its opposite ends bent at an anglethe'reto, as at 14, said bent portions 1 1 being slightly curved for engaging the interior of the opening communicating with the flue or chimney, in order to hold the devrce in proper position. The strip 13' is slightly bowed so as to extend away from the plate 11 at its outer ends, inorder that the angled portions 14 will bind'against the in terror of the flue opening when a pressure applied that would tend to remove the device from the flue opening i 'it ES to be noted that by providing the link connections between the cover plate and i the heat receiving plate said heat receiving plate may be adjusted with relation to the cover plate in order to fit flue openings of various depths, and that said heat receiving plate may be folded adjacent the cover plate when not in use.

lVhen it is desired to place my device at a flue opening, the heat receiving plate 11 is inserted in the opening, which will cause the spring strip 13 to be slightly flexed or bowed,

as the opposite ends of said strip engage the interior of the flue opening, until the flange 6 on the cover plate 5 engages the wall of 'the room adjacent'the flue opening. When in this position the device will be held againstaccidental displacement due to the fact that the angled portions 14 will bind against the interior of the flue opening when a pressure is exerted on the device for removing the same. By providing the plate llthe intense. heat 1n the chimney will not contact with the cover plate 5, thus preventing fire and pre surface of the serving the outer finish or cover plate.

Having thus described my invention, what 'I claim as new is:

A flue stop structurecomprising a- ,cover plate, a heat plat-e, a resilient strip'atta-ched to the heat plate and having end portions disposed beyond the opposite side edges of the heatplate and a plurality ofseries ct links pivotally connected with each otherone series being disposedfat one side of the strip and the other series beingdisposed at the opposite side of the strip and both series of 7 terminal links of each series beingconnected lapsed,

,7 links being pivotally connected with the links are restrained to swing transversely of ,coverplate and heat plate respectively the the resilient strip when the structure is 001- In testimony whereofll have aflixed my with the cover plate and the heat plate respectively and the axes of the pivots besignature. tween the links being disposed parallel with l the length of the resilient strip whereby the f LEWIS I.
